Efficient heavy wash oil condensing device

Abstract

The invention discloses an efficient heavy wash oil condensing device. The efficient heavy wash oil condensing device comprises a pressurizing impurity remover and a condenser body, a discharge outlet of the pressurizing impurity remover is connected with an inlet of the condenser body through a material conveying pipe, and a condensing pipe is installed at the middle of a condensing chamber in the condenser body; a discharge outlet which is cut in the lower portion of the side, far away from a feeding inlet, of the condenser body is connected with a distribution conveying device through a discharge pipe, and a lower discharge outlet of the distribution conveying device is connected with a feeding inlet of a first oil-water separator through a conveying pipe; and an impurity removing port at the bottom of the pressurizing impurity remover is connected with a feeding inlet of a second oil-water separator through a guide pipe, an oil outlet of the second oil-water separator is connected with an inlet of a second membrane filter through a guide pipe, and a discharge outlet of the second membrane filter is connected with an external storage through a guide pipe. According to the efficient heavy wash oil condensing device, separation of products and water is conducted through the first oil-water separator and the second oil-water separator, moisture in the products is reduced, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of condensing devices, and in particular relates to a high-efficiency heavy washing oil condensing device. Background technique [0002] Fractions in coal tar or petroleum, 230-300 ° C, no clear use was found in the early stage, using its similar miscibility with coal tar and other components in petroleum to wash the gas generated during the fractionation process, Make it absorb benzene, naphthalene and other substances in the gas, so it is named washing oil, and now it is mainly used as a term in the coal tar industry. [0003] Heavy washing oil is generally obtained by distillation of coal tar or petroleum, and condensation work is required during distillation. The condensation efficiency of the condensing device used for condensation of heavy washing oil is low. When the steam to be condensed enters the interior of the condensing device, the temperature is too high It will greatly reduce the efficiency o...

Problems solved by technology

[0003] Heavy washing oil is generally obtained by distillation of coal tar or petroleum, and condensation work is required during distillation. The condensation efficiency of the condensing device used for condensation of heavy washing oil is low. When the steam to be condensed enters the interior of the condensing device, the temperature is too high It will greatly reduce the condensation efficiency. When the heavy washing oil is condensed, a small amount of water can condense together, which is difficult to separate. If the condensed water is discharged directly, the condensed water contains a small amount of heavy washing oil, which will pollute the environment.
